I hope DanaDark from the WWM team allows me to quote him, because he points out, why it is actually impossible to create a running WWM or RN version for DW. Both mods have the same problem:
So this is the major problem, why I can't present you a DW version of that mod. We have to wait for the next game patch that changes the mentioned limitation.The current issue being faced is the QUAD issue. Basically the map is cut up in squares of a certain size (each called a quad) and in each square, there can ben no more than 60 provinces. Supposedly this has always been an aspect of the game, but I believe it was broken so it never bothered any mods. Seems it was fixed and so when WWM, as well as others mods, try to run, it cant due to violating this hard coded limitation. So the latest version of WWM hinges on IF the devs will change that or not. If they do, the newest version could be out rather quickly. If not, the entire map needs to be checked over and modified to fit these rules.
